  Trigger Sensitivity: 30 mV p-p (10 mV p-p on special order)

  Over Voltage Protected: ± 30 VDC

OPTO-ISOLATED DC PULSE INPUT

  High (logic 1): 4-30 VDC

  Low (logic 0): Less Than 1 VDC

  Minimum Current: .5 mA

  Hysteresis: 0.4 VDC

  Frequency Range: 0 to 5 kHz  

  Min. Pulse Width: 0.1 msec

CONTACT CLOSURE INPUT (contact closure to common)

  Internal Pullup Resistor: 100 KΩ to +3.6 VDC

  High (logic 1): Open or 4-30 VDC

  Low (logic 0): Less Than .5 VDC

  Internal Switch Debounce Filter: 0 to 40 Hz

NOTE

:   Sustained contact closure will shorten 

   

battery life.

RESET INPUT (contact closure to common)

  Internal Pullup Resistor: 100 KΩ to +3.6 VDC

  High (logic 1): Open or 4-30 VDC

  Low (logic 0): Less Than .5 VDC

K-FACTOR

  Range: 0.001 to 99999999

  Decimal Point Locations: XXXX.XXXX to XXXXXXXX

20 POINT LINEARIZATION -LIN OPTION

  This  feature  allows  the  user  to  enter  20  different  frequencies 

with 20 different corresponding K-Factors to linearize non linear 

signals.

ANALOG OUTPUT -MA OPTION:

  Type: 4-20 mA follows rate display, Two wire hookup

  Accuracy: 0.025% Full Scale at 20° C

  Temperature Drift:  50 ppm/°C Typical

  Reverse Polarity Protected

  Update Rate: 8 times/second

NOTE:

 The DPF500 uses the 4-20 mA loop power as its primary 

power source when this option is used.  The battery is still 

required for standby battery operation.

DATA STORAGE:

  Setup Information: Stored in fl ash memory

  Totalizer:  Stored  in  battery  backed  RAM  but  can  be  saved  to 

fl ash memory by operator for recall after battery change out.

The above table is shown with pulse output inactive. Use 

of pulse output shortens battery life.

 

Example: A pulse output of 0.06 sec. duration, once per 

second, would derate the battery life by 20%.
